Specification of Letters Patent.

Application filed June 28, 1911; Serial No, 635,757.

1 b all whom it may concern Be itknown that I, CHRISTOPHER IV. LE-vaLLiii', a citizen of the United States, residing at Milwaukee, in thecounty of Milwaukee and State of Visconsin, have invented certain newand useful Improvements in Inhalers, of which the following is aspecification,

The object of my invention is to produce an inhaler that can beconveniently carried in the pocket. and is adapted for use in thetreatment of throat, nasal and lung diseases, and which may be used forinhaling either through the mouth or the nostrils.

In the accompanying drawings, wherein the preferred embodiment of theinvention is illustrated, Figure 1 is a side View of the inhaler. Fig. 2is a longitudinal section of the same. Fig. 3 is a perspective view ofthe perforated stopper. Fig. 4: is a perspective view of the porousholder for the medicament that may be employed.

In the drawings, 2 designates a hollow container adapted to receive apiece of sponge, 3, or other porous and absorbent substance which is tobe charged with the medicament that it may be desired to use in thetreatment of whatever disease the inhaler is used to alleviate. One endof the container is shaped into a neck 5 to receive a cap at. The neckmay be screw-threaded and the cap correspondingly threaded to engagetherewith, as indicated in Fig. l, or it may be smooth as represented inFig. 2. A rib or flange 6 preferably separates the neck of the containerfrom the main body thereof in order to limit the extent to which the capmay be forced upon the neck. The cap is hollow and its outer end isperforated, as indicated at 7. The outer end of the container islikewise perforated, as indicated at 8.

It sometimes happens that the liquid taken up by the absorbing holder,3, drains therefrom into the inhaler and tends to escape through theopenings 7 and 8. As this is objectionable for many reasons I haveformed the container 2 and the cap 4, which are preferably made fromsome noncorrosive metal,as indicated in the drawings, that is, theperforated end of each of these parts is inturned immediately around theaperture, forming internal drip or collecting grooves 9, 9'.

10 designates a stopper through the longitudinal center of which isformed an aperture 11. This stopper is inserted into the neck of thecontainer 2, and may be of a length to extend beyond this neck and intothe cap 4 when seated upon the neck, as indicated in Fig. 2. The stoppermaintains the absorbent holder 3 in place and also tends to prevent thefree passage into the cap of any liquid which may drain from the holder.

The holder 3 may be provided with a loop 12 to which is secured a cord13, these serving as means by which the holder may be easily withdrawnfrom the container.

The container is preferably tapering in exterior configuration and is ofa size adapting it to be inserted into a nostril. The cap is shaped tobe held between the lips when the inhalations are taken through themouth. I have found it of advantage to provide the cap with an exteriorgroove 1 so that the inhaler may be securely held by the teeth whilebeing used.

From the foregoing description and an examination of the drawings itwill be seen that the inhaler that constitutes the subject of myinvention is very simple in construction, and moreover, the partsthereof are easily separable and of such shape as to be readily cleanedand sterilized.

\Vhat I claim is:

1. In an inhaler, the combination of an open ended container providedwith a neck, an absorbent holder within the container, a cap fitting theneck of the container, and a centrally perforated stopper fitted in theneck of the container, the container and the cap being perforatedattheir ends, substantially as set forth.

2. In an inhaler, the combination of a tapering container adapted to fitthe nostril, its smaller end being perforated and inturned about theperforation and its larger end formed with a neck, a cap fitting thesaid neck and having its outer end inturned and perforated and shaped toconstitute a mouth piece, a porous holder for the medicine in thecontainer, and a perforated stopper between the porous holder and themouth piece, substantially as set forth,
